If Indian/Paki didn't had South India admixture, would they look Persian, Iranic?
South Asian descent of Paki, Indian, Rohingya, Sri Lankan, Bengali are all dark skinned
Pakistani/North Indian have large portion of Iranic/West Asian component but also signficant 30-50% of South Indian admixture but many of them look more like middle easterners.
Take a look at the genetics of Sindhi. What makes modern South Asian people distinct are their South Indian admixture otherwise today they look just like middle easterner or North Caucasus

The Sindhi have 55-60% West Asian Iranic, 35-38% South Indian admixture.
And many Sindhi people do look more Middle easterner
